Baking powder overdose

Definition

Baking powder is a cooking product that helps batter rise. This article discusses the effects of swallowing a large amount of baking powder. Baking powder is considered nontoxic when it is used in cooking and baking. However, serious complications can occur from overdoses or allergic reactions.

This article is for information only. DO NOT use it to treat or manage an actual poison exposure. If you or someone you are with overdoses, call the local emergency number (such as 911), or the local poison control center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States.

Alternative Names

Sodium bicarbonate

Poisonous Ingredient

Baking powder contains sodium bicarbonate (also found in baking soda) and an acid (such as cream of tartar). It may also contain cornstarch or a similar product to keep it from clumping.

Where Found

The above ingredients are used in baking powder. They may also be found in other products.

Symptoms

The symptoms of a baking powder overdose include:

Home Care

Seek medical help right away. Do not make a person throw up unless poison control or a health care provider tells you to do so.

If the person can swallow, give them water or milk right away, unless a provider tells you not to. Do not give water or milk if they have symptoms that make it hard for them to swallow. These include vomiting, having convulsions, or a decreased level of alertness.

What to Expect at the Emergency Room

Take the container with you to the hospital, if possible.

Your provider will measure and monitor your vital signs, including temperature, pulse, breathing rate, and blood pressure. You may receive:

Blood and urine tests
Electrocardiogram (ECG)
Intravenous fluids (through a vein)
Medicines to treat symptoms

Outlook (Prognosis)

The outcome of a baking powder overdose depends on many factors, including:

Amount of baking powder swallowed
Person's age, weight, and overall health
Type of complications that develop

If nausea, vomiting, and diarrhea are not controlled, serious dehydration and body chemical and mineral (electrolyte) imbalances may occur. These can cause heart rhythm disturbances.

Keep all household food items in their original containers and out of the reach of children. Any white powder may look like sugar to a child. This mix up could lead to accidental ingestion.
